Chapter 3 Storage Management
Working with Volumes
Notice When Creating Volumes
• To create a volume, use RAID Builder instead of the Disk Management option in Windows Storage Server.
• When volumes are deleted, formatted, or changed to another volume type, all data stored on the volumes is
erased. Before executing these operations, back up any important data.
• In this manual, “recover” means reverting the TeraStation (including data) to its former state prior to the drive
failure. It doesn’t refer to reading data from a failed drive.
Volume Types
RAID 6 Volumes
RAID 6 distributes two parity blocks when writing data. The usable space is equal to the sum of the capacity of four
drives. If two drives in a RAID 6 volume fail, data on the volume can be recovered after the failed drives are replaced.
However, if three or more drives fail, all data is lost.
RAID 5 Volumes
RAID 5 distributes a parity block when writing data. The usable space is equal to the sum of the capacity of the five
drives. If one drive in a RAID 5 volume fails, data on the volume can be recovered after the failed drive is replaced.
However, if two or more drives fail, all data is lost.
RAID 10 Volumes
Mirrored pairs of drives in RAID 1 volumes are combined into a RAID 0 volume. The usable space is equal to the
capacity of three drives. The same data is written to multiple drives so that if one drive from either or both RAID 1
volume fails, data on the volume can be recovered after the failed drives are replaced. However, if two drives on the
same RAID 1 volume or three drives in total fail, all data is lost.
Striped Volumes
RAID 0 stripes data across the multiple drives, but lacks parity blocks like RAID 5 or RAID 6. The usable space is equal
to the capacity of all drives on the TeraStation. RAID 0 doesn’t have any redundancy so data cannot be recovered if
even a single drive fails.
Creating a Volume
To create a volume, follow the procedure below. Successfully following the procedure will erase all data stored on
the volumes.
